Abstract
The utility model especially relates to a novel peel off under scope mucous membrane and use high frequency electric cutter. This novel peel off under scope mucous membrane and use high frequency electric cutter, including circular telegram cutting edge, handle, circular telegram cutting edge longitudinal section is the type type, and the cross section is the flat structure, and the head end of circular telegram cutting edge is an insulation portion, and both sides set up the conductive filament. The utility model discloses electric knife front end longitudinal section is the flat head of type, easily separates the alimentary canal submucosa, the head end is an insulation portion, and this electric knife of being convenient for when separation alimentary canal submucosa, is difficult for perforating, the cutting is removed to the easy cutting edge both sides that set up of both sides conductive filament, very big improvement cutting efficiency, horizontal conductive filament not only does benefit to and impels the cutting, raises the efficiency, and having reached of initiating is moreover controlled, the purpose of multi -direction cutting forward, is so far, and the electric knife can't be accomplished, is worth promoting.
Description
(1) technical field
This utility model relates to the medical apparatus and instruments of a kind of Endoscopic submucosal dissection, particularly to stripping high-frequency electrical cutting knife under a kind of Novel endoscope mucosa.
(2) background technology
Decollement under endoscopic mucosal, is the new treatment means occurred in recent years, is also the good technology of potential applicability in clinical practice, allow more early stage digestive tract cancer can on scope once property excise completely, eliminate the misery of abdominal and the excision of organ.Under endoscopic mucosal, to have wound little for decollement, patient can accept multiple position and repeatedly treats, make doctor obtain complete histopathology specimen for analysis, for area is relatively big and form is irregular or merge ulcer, the tumor of cicatrix carry out more than 96% resection rate, to reduce the advantages such as recurrence probability.
Pass through scope, first labelling is carried out by coagulation method at perilesional, submucosal injection makes pathological changes swell afterwards, various electric knife is utilized to cut mucosa along labelling position annular, mucous layer and Submucosa is made to be partially separated, continue to submucosal injection, make the pathological changes being cut through swell further, finally make pathological changes excise completely.Postoperative Operated Specimens is carried out histopathologic examination, it is judged that whether pathological changes excises completely.Under endoscopic mucosal, decollement expands the pathological essence to digestive tract superficial foci and the research of development trend, has deepened the understanding to the origin of digestive tract infantile tumour, generation and development, improves the level of basic research and clinical practice.
Peel off surgical technic difficulty under endoscopic mucosal high, be primarily present following problems point:
(1) needing doctors and nurses skillfully to use apparatus, need first to make diseased region swell with entry needle injection, be inserted into electric knife and cut after extracting entry needle out during operation, formality is more complicated, and efficiency is low；
(2) depth of cut is relatively difficult to hold, it is possible to injure lower-hierarchy.
(3) utility model content
This utility model is in order to make up the deficiencies in the prior art, it is provided that stripping high-frequency electrical cutting knife under the Novel endoscope mucosa of a kind of easy to use, simple in construction.
This utility model is achieved by the following technical solution:
Peeling off under a kind of Novel endoscope mucosa and use high-frequency electrical cutting knife, including energising blade, handle, it is characterized in that energising blade longitudinal section is convex, and cross section is flat structure, and the head end of energising blade is insulation division, and both sides arrange conductive filament.
Stripping high-frequency electrical cutting knife under described Novel endoscope mucosa, also includes switch.
Described energising blade both sides conductive filament forms vertical electric knife portion and horizontal electric knife portion, insulation division, vertical electric knife portion, horizontal electric knife portion length ratio be 1:1.8-2.3:0.7-1, two horizontal electric knife portions are on a horizontal line.
The beneficial effects of the utility model are: longitudinal section, this utility model electric knife front end is convex flat head, it is easy to separating digesting road tela submucosa；Head end is insulation division, it is simple to this electric knife, when separating digesting road tela submucosa, is not easily bored a hole；The setting of both sides conductive filament is prone to the cutting of blade two side shifting, greatly improves cutting efficiency；Horizontal conductive filament is not only beneficial to propelling cutting, and raising efficiency, and the pioneering purpose having reached left and right, multi-direction cutting forward, be so far, and electric knife cannot be accomplished, is worthy to be popularized.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Accompanying drawing 1 is the structural representation of energising blade of the present utility model；
Accompanying drawing 2 is the top view of accompanying drawing 1 of the present utility model；
In figure, 1 insulation division, 2 conductive filaments.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment includes energising blade, handle, and energising blade longitudinal section is convex, and cross section is flat structure, and the head end of energising blade is insulation division 1, and both sides arrange conductive filament 2.
Stripping high-frequency electrical cutting knife under described Novel endoscope mucosa, also includes switch.
Described energising blade both sides conductive filament 2 forms vertical electric knife portion and horizontal electric knife portion, insulation division, vertical electric knife portion, horizontal electric knife portion length ratio be 1:1.8-2.3:0.7-1, two horizontal electric knife portions are on a horizontal line.
The beneficial effects of the utility model are: longitudinal section, this utility model electric knife front end is convex flat head, it is easy to separating digesting road tela submucosa；Head end is insulation division 1, it is simple to this electric knife, when separating digesting road tela submucosa, is not easily bored a hole；The setting of both sides conductive filament 2 is prone to the cutting of blade two side shifting, greatly improves cutting efficiency；Horizontal conductive filament 2 is not only beneficial to propelling cutting, and raising efficiency, and the pioneering purpose having reached left and right, multi-direction cutting forward, be so far, and electric knife cannot be accomplished, is worthy to be popularized.
